Hi all

My escort van has started playing me up for the last 3 months. It started getting sluggish so i put a can of injector cleaner in what a mistake that was it vertualy killed it ,coughing,spluttering,wouldnt start , smoking like a bonfire , after being towed home the rac had a look he bypassed the fuel filter and all was ok for an hour then it went back to all the mentioned problems. So then my local garage had it in all the injectors were blocked so they were all sorted all new filters and pipes £250 later all was ok for about a week. Then it has since gone sluggish again 70 flat out on the flat 50-60 up hills . It just seems to me that something is just not fireing correct like in a petrol engine that is miss firing .Also my biggest concern is the drop in fuel consumption i used to get 475-540 to a tank now it is down to 360-380 . I have spoke to my local garage and the reply was it must be the fuel pump very expensive to sort out . Can a fuel pump make this happen i think it is something very simple that has been overlooked but i know nothing about engines so im useless. Could someone shed any light on this or is the end of the life for the van coming.

Thanks phil
